Q

Commencez par processing.app.Sketch.setModified dans Sketch.java:760 et suivez le chemin de création de l’éditeur de JavaEditor et JavaMode indiqué dans la stack trace. Reproduisez l’échec en ouvrant un sketch via le menu de l’éditeur, puis établissez le comportement attendu lorsque current est null et vérifiez que l’ouverture ne lève plus cette exception.
